Answer
Hi Rob;

They are not harmful to your fish in any way and are not really parasites so don't worry. A parasite is "an organism that lives in or on and takes it's nourishment from another organism". These critters feed on the waste your fish make and not on the fish themselves. They are simply scavengers that are doing an important job. It is perfectly fine for the fish to eat them. It's what they would do in nature too. Just another link in the food chain.
